The answers here have the correct information regarding the line length, however none of them provided me with the sufficient code snippet to fix the issue. I looked around and found the best way to do this, here it is;

".$eol;
$headers .= "Content-Type: multipart/alternative; boundary=\"$separator\"".$eol;
$headers .= "--$separator".$eol;
$headers .= "Content-Type: text/html; charset=utf-8".$eol;
$headers .= "Content-Transfer-Encoding: base64".$eol.$eol;

// message body
$body = rtrim(chunk_split(base64_encode($html)));

mail($email, $subject, $body, $headers);
// ==============================================
